Since the 1970s, Lego has created countless products with various motifs such as occupations, ethnic costumes, and movie characters.
The three that I liked the most were “Egyptian nemes headdress” (page 70) from 1998, “Ninja throwing star” (page 72), and “Emperor Palpatine” (page 138) from the 2008 Star Wars series.
It's very interesting to pay close attention to details such as Lego's costumes, hairstyles, and color schemes. It's difficult to collect them all, but if you purchase this book, you can enjoy Lego World.
